4608H-701-101/470L

Overview

The Bourns 4608H-701-101/470L is an RC network terminator designed for low-noise termination in CMOS circuits. It features a single-ended configuration with seven resistor-capacitor elements housed in an eight-pin Single Inline Package (SIP) for through-hole mounting. The component provides a resistance of 100 ohms and a capacitance of 47 picofarads per element, operating at a maximum voltage of 50 volts. Resistors maintain a standard tolerance of ±5%, while capacitors utilize C0G dielectric characteristics with a temperature coefficient of 30ppm/°C and a tolerance of ±20%. This design integrates passive components to save space and reduce insertion time.

Feature Summary

• Integrates resistors and capacitors into a single SIP package to minimize board space requirements
• Provides low noise termination specifically optimized for CMOS circuit applications
• Includes insulation resistance testing to ensure long-term reliability

Applications

• Low noise termination for CMOS logic circuits
• EMI suppression in digital signal lines
• RC filtering in high-speed data transmission interfaces

Procurement Notes

Verify the specific suffix '470L' against the manufacturer's current datasheet to confirm exact capacitance values and lead finish specifications. Ensure the ordering part number matches the required pin count and termination style for your PCB layout. Confirm RoHS compliance status if restricted materials are prohibited in your assembly process. Cross-reference the resistance value '101' code to validate the 100 ohm specification before procurement.

Selection Notes

Select this component when a single-ended RC terminator is required for CMOS bus lines. The 100 ohm resistance and 47 pF capacitance combination targets specific impedance matching needs. Consider the 8-pin SIP form factor for through-hole assembly constraints. Evaluate the 50-volt maximum rating against the system's operating voltage to ensure adequate safety margins. Compare against other series variants if different pin counts or resistance values are needed.

Part Context

This component belongs to the Bourns 700 Series of RC Terminator Networks. The series offers various pin counts ranging from 4 to 16 pins to accommodate different channel requirements. These networks are engineered to replace discrete resistor and capacitor assemblies, simplifying the bill of materials and reducing assembly complexity for electronic designs requiring effective EMI filtering and signal termination.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the 100 ohm resistance, 47 pF capacitance, and 8-pin SIP footprint. Consult the manufacturer for updated lifecycle status as availability may vary.
